Understanding the Roman Numeral System
The Roman numeral system uses combinations of letters from the Latin alphabet: I, V, X, L, C, D, and M. This system doesn’t follow the base-10 format but is instead an additive and subtractive method of denoting numbers.
Letter | Value |
---|---|
I | 1 |
V | 5 |
X | 10 |
L | 50 |
C | 100 |
D | 500 |
M | 1000 |
For example, the number 9 is written as IX (10 – 1), while 11 is XI (10 + 1). Understanding this structure helps users verify the output of converter tools.
Why Roman Numerals Still Matter
Despite being ancient, Roman numerals are still highly relevant. They’re used in:
- Movie titles (Rocky II, Star Wars Episode IV)
- Monarch names (Queen Elizabeth II)
- Clocks and watches
- Book chapters and introductions
- Olympic games (e.g., XXV Olympiad)
Because of their formal appeal and traditional value, many institutions still rely on Roman numerals in official branding and documentation.
